Parameter Comparison

Engineering Selection Recommendations

SCS7TT93HPL2TLS03F (Recommended Primary Substitute)

This part is the closest functional equivalent to the SCS8TT93HPL2T0S03F. Both components share the LM102A series designation, identical package footprint (0505 / 1313 Metric), matching forward voltage (5.9V), and equivalent test current (150mA). The primary difference is packaging format: SCS7TT93HPL2TLS03F is supplied in Cut Tape format versus the original Tape & Reel format. Both parts are RoHS Compliant and carry identical MSL ratings. The SCS7TT93HPL2TLS03F exhibits slightly higher luminous flux (119 lm vs. 111 lm) and improved efficiency (134 lm/W vs. 125 lm/W), with the trade-off of lower CRI (70 vs. 80). Both parts are classified as obsolete, indicating limited long-term availability.

SCP8TTJ5HEL1TUPF6E (Alternative Substitute)

This part represents a different product series (LH231B) with significantly different electrical and optical characteristics. The SCP8TTJ5HEL1TUPF6E operates at lower forward voltage (2.9V vs. 5.9V) and higher test current (700mA vs. 150mA), requiring circuit redesign for direct substitution. The package footprint is substantially larger (1111 / 2828 Metric vs. 0505 / 1313 Metric), which may not fit existing PCB layouts. However, this part delivers higher luminous flux (320 lm vs. 111 lm) and superior efficiency (158 lm/W vs. 125 lm/W), with CRI matching the original specification (80). The SCP8TTJ5HEL1TUPF6E is classified as Active, providing superior long-term availability compared to obsolete alternatives. ROHS3 compliance exceeds the original RoHS Compliant status.

Selection Criteria:

• For direct PCB compatibility and minimal circuit modification: Select SCS7TT93HPL2TLS03F
• For enhanced performance and long-term availability: Select SCP8TTJ5HEL1TUPF6E (requires PCB redesign and circuit parameter adjustment)

Frequently Asked Questions (FAQ)

Q: Can SCS7TT93HPL2TLS03F be used as a direct drop-in replacement for SCS8TT93HPL2T0S03F?

A: Yes. Both parts share identical package dimensions (0505 / 1313 Metric), forward voltage (5.9V), test current (150mA), maximum current (250mA), viewing angle (145°), and thermal resistance (2°C/W). The primary difference is packaging format (Cut Tape vs. Tape & Reel). PCB footprints and circuit connections are identical. Luminous flux output is slightly higher (119 lm vs. 111 lm), and efficiency is improved (134 lm/W vs. 125 lm/W). CRI is lower (70 vs. 80).

Q: What are the key differences between SCS7TT93HPL2TLS03F and SCP8TTJ5HEL1TUPF6E?

A: These parts differ significantly in electrical and optical specifications. SCS7TT93HPL2TLS03F maintains the same series (LM102A) and package size as the original part, while SCP8TTJ5HEL1TUPF6E uses a different series (LH231B) with a larger package (1111 / 2828 Metric). Forward voltage differs (5.9V vs. 2.9V), test current differs (150mA vs. 700mA), and luminous flux is substantially higher in the SCP8TTJ5HEL1TUPF6E (320 lm vs. 111 lm). Direct substitution of SCP8TTJ5HEL1TUPF6E requires circuit redesign.

Q: Why is the SCS8TT93HPL2T0S03F classified as obsolete?

A: Product status is provided in the manufacturer data. Obsolete classification indicates the part is no longer in active production. Both substitute options (SCS7TT93HPL2TLS03F and SCP8TTJ5HEL1TUPF6E) are listed in Samsung Semiconductor inventory, with SCP8TTJ5HEL1TUPF6E classified as Active for continued availability.

Q: Are all three parts RoHS compliant?

A: Yes. SCS8TT93HPL2T0S03F and SCS7TT93HPL2TLS03F are RoHS Compliant. SCP8TTJ5HEL1TUPF6E is ROHS3 Compliant, which represents an enhanced compliance standard.

Q: What is the significance of the MacAdam Ellipse specification?

A: MacAdam Ellipse defines color tolerance around the nominal 4000K color temperature. SCS8TT93HPL2T0S03F has no MacAdam Ellipse specification listed. SCS7TT93HPL2TLS03F specifies 5-Step MacAdam Ellipse (wider tolerance), and SCP8TTJ5HEL1TUPF6E specifies 3-Step MacAdam Ellipse (tighter tolerance). Tighter tolerance indicates more consistent color output across production batches.

Q: Can SCP8TTJ5HEL1TUPF6E fit in the same PCB footprint as the original part?

A: No. SCP8TTJ5HEL1TUPF6E uses package 1111 (2828 Metric) with dimensions 0.110" L × 0.110" W, compared to the original 0505 (1313 Metric) package with dimensions 0.053" L × 0.053" W. The substitute part is approximately 2.1 times larger in each dimension. PCB layout modification is required.

Q: What is the impact of lower CRI in SCS7TT93HPL2TLS03F?

A: CRI (Color Rendering Index) of 70 versus 80 indicates reduced color rendering accuracy. The original part (CRI 80) provides better color fidelity for applications where accurate color representation is critical. SCS7TT93HPL2TLS03F (CRI 70) is suitable for general illumination where color accuracy is less critical. SCP8TTJ5HEL1TUPF6E maintains CRI 80, matching the original specification.

Q: What is the MSL (Moisture Sensitivity Level) rating, and why is it important?

A: All three parts carry MSL 2A (4 Weeks), indicating the component can be exposed to ambient conditions (23°C / 50% RH) for up to 4 weeks before soldering without baking. This specification is critical for supply chain management and assembly process planning. Identical MSL ratings across all parts ensure compatible handling procedures.

Q: Which substitute part should be selected for new designs?

A: For new designs, SCP8TTJ5HEL1TUPF6E is recommended due to Active product status, ensuring long-term availability and supply chain stability. The higher luminous flux (320 lm) and efficiency (158 lm/W) provide performance advantages. However, circuit design must accommodate the lower forward voltage (2.9V vs. 5.9V) and higher test current (700mA vs. 150mA). For legacy product support requiring minimal circuit modification, SCS7TT93HPL2TLS03F is appropriate.
